Attribut:Has type
From Semantic MediaWiki - Sandbox
"Has type" is a predefined property that describes the datatype of a property and is provided by Semantic MediaWiki. This property is pre-deployed (also known as special property) and comes with additional administrative privileges but can be used just like any other user-defined property.

This is just an example that besides the entity specification change group (that watches changes on all properties specification), one can add an individual group to watch all changes on property types.
